How is it disconnected?
You may find that your code-behind says that it is disconnected but it will retry automatically until it hooks up. Just suppress the errors if that's the case

In my code, SignalR connection stops automatically after some time when running from Visual Studio

It can time out. Is that what's happening? The only way that would happen is either it loses connection to the server or the code has stopped running (crashed or debugging)

Solution 1

Before each call check wheather it is disconnected then start it again as follows
and continue

$.connection.hub.disconnected(function () {
$.connection.hub.start();
});

Solution 2

OK
just replace your following line

$.connection.hub.start()

with

following

$.connection.hub.disconnected(function () {
$.connection.hub.start();
});

Hope this is clear.
